In addition, the undocumented "neutral" is also accepted as a valid language setting. That is also the default value if the INI setting is not set:<?phpvar_dump( mb_language( 'neutral' ) ); // TRUE; accepted as language stringvar_dump( mb_language() ); // 'neutral'?>

The documentation of this particular INI setting and function is ambiguous.
